Masticatory performance of different impression methods for complete denture fabrication: A randomized controlled...

Area of Science:

• Dentistry
• Prosthodontics
• Biomaterials

Background:

• Complete dentures are essential for edentulous patients.
• Impression techniques significantly influence denture fit and function.
• Evaluating different impression methods is crucial for optimizing complete denture fabrication.

Purpose of the Study:

• To compare the masticatory performance and related factors of complete dentures fabricated using conventional versus simplified impression methods.
• To assess the impact of two distinct impression techniques on occlusal contact area, maximum occlusal force, and perceived chewing ability.

Main Methods:

• A crossover randomized controlled trial involving edentulous patients requiring complete dentures.
• Conventional method: custom tray, border molding, impression compound, and silicone. Simplified method: stock tray and alginate.
• Assessment of mixing ability (masticatory performance), maximum occlusal force, occlusal contact area, and perceived chewing ability.

Main Results:

• The conventional method resulted in a significantly larger occlusal contact area compared to the simplified method.
• No significant differences were found between the two methods regarding mixing ability, maximum occlusal force, or perceived chewing ability.

Conclusions:

• Complete dentures fabricated with the conventional impression method demonstrate a superior occlusal contact area.
• The conventional method may lead to fewer post-insertion adjustments, potentially enhancing early denture stability.
